    ...all the required coding and was a programming language that I enjoyed using. I was not entirely confident about some parts of the task, especially building a graphical user interface, but decided to face my fears, trusting to Python's maturity, powerful libraries, and third-party support. The SPE editor together with Python's interpreted nature proved especially valuable.

    ...ally on the recommendation of a friend, Steve Madere, who had founded Dejanews.com (now a part of Google). Describing the rationale for his choice, Curt said "I looked at Java and C and came to the conclusion that 1 line of Python is 10 lines of Java or 100 lines of C. Developers write code at basically a constant rate so I chose Python which was (and is) the highest level language I've ever seen that is also flexible enough to be generally useful." Architecture From the beginning, T...

Tools not Written in Python The good experiences with the Python-based tools are confirmed by other projects originally coded in C++. The development of TTP-Load, the download tool, started in 1999.

  • Comparing Python to Other Languages

    ...alltalk Perhaps the biggest difference between Python and Smalltalk is Python's more "mainstream" syntax, which gives it a leg up on programmer training. Like Smalltalk, Python has dynamic typing and binding, and everything in Python is an object. However, Python distinguishes built-in object types from user-defined classes, and currently doesn't allow inheritance from built-in types. Smalltalk's standard library of collection data types is more refined, while Python's library has more...

Python is a very productive way to write code. Support for Selective Optimization: We knew there was a chance that profiling would later reveal that small portions of our application were time-critical, and therefore might need to be re-coded in C or C++. Python integrates seamlessly with these languages, so you truly can "...

This is especially true if you plan to teach Python as an introductory language (say in a CS-1 course), since Python 3 is the future of Python. Also, if you teach Python in languages other than English, where non-ascii characters could be put to good use in writing identifiers, then Python 3 should definitely be your choice.
